- Application filed January 17, 1924. Serial No. 686,732.

This invention relates 'to a doorbumper" and registering devlce more commonly known ;.to the-trade as a dove-tail. The prior art shows devices of thls "char I 6 acter which vare provided with a keeper socket for the purpose of thrusting'against the strikercarried by the door in a plane transverse to the plane of the door.

,This invention relatesto an improvement 10 over the old form of bumper and registering device, in thatthe keeper socket is constructed in such'a way as to thrust against the door in a plane transverse to the plane of the door andalso in a plane parallel to the plane of; the door. This will prevent the door from rattling .or vibrating on its: a U hinges in a line parallel to the "plane of the v ,er socket'is in the form of astamped-out pro-' door. The' line of thrust transverse to the plane of'the. door serves the same purpose as in the prior 'art. The improvement.re-

sides'in th'e two-way thrust which thoroughly eliminates all .door rattling. 'My 'mproved form of and from the description it will be seen that...

vthis taper in the plane parallel to the plane of the door enables the Jm'anufa'cturer to make thestriker of a' stamping as the taper enables the stamping to be withdrawn quite readily from the dies.

In the 'drawings: 7 jv f Fig. 1 is a perspective view of a portion of an automobile body showing my improved striker and keeper socket'installed therein.

Wear ,ing or grip plates e are fitted on these? rub ber blocks, the inherent resiliency of "the I striker is well adapted to this-form 0f keeper socket and enables me to form the striker of a stamp ing, because of the fact that thekeeper rubber blocks forcing the grip plates 0 towardseach other. As shown in Fig. 2, the platea is cut away as at f to expose these grip-plates so, that the'strikerg carried by the "door; may engage between the two grip I plates; and wedge therein, the yieldable rub- "berblocks resisting the wedging action.

The grip", plates form the. side walls of the keeper socket and as shown in the drawing s, these walls convergein two directions,

toiwit,-in a line parallel to the plane of the door and in a linetransverse to the plane of the door. This is what I call a two-way taper. x

As shown in Fig. 5, the striker plate 9 is -made of a' stamping; the striker a: which engagesbetween the grip plates of the keepjection, the side walls of sa'i striker converging in a line parallel to the plane of thG'dOOI', and in alineftra-nsverse to the I -line parallel in) the plane of the door is more clearly shown in Fig. 3'and it will be evident from this that thestriker maybe readily forined of agstaniping since this stamping may ti'ef withdrawn from the dies after the"struck"out striker is formed in the striker plate. 3

The resilient rubber blocks'thrust against the grip plates and consequently thetaper corresponding taper of the'socket and strik- -;,Ihe w g-tor: this is aa evident.

In addiv I i a plane transverse thereto because oft-he the line of" v (fer in a line transverse to the plane of the p er-socket carried bylthel door. post, and the g tion, the thrust is exerted in a plane parallel gripping members converging toget erin the direction of impact of the striker and diverging outwardly from the door post in the plane of the door opening, the said keeper and the gripping members so arranged to afford the gripping members a yielding action flnember with tapered Walls converging in and a striker member comprising a plate for the mounting of same and a striking por tion comprisin a projection tapered from end to end and having its walls also converging toward the outside-of the projection, the said converging faces of both the gripping members and this projection of the striker being substantially complementary, whereby when the two inter-engage the yielding force of the gripping members serves to stress the door both outwardlyin its path of opening and compressively in the plane of the door opening.

2. In a door bumper or dovetail, the comopening, and a' striker provided with a proection and in the form of a stamping in which the projection is formed as a hollow I the direction of the impact and also converging laterally outwardly from the face of the striker to form complementary engaging surfaces for striker and keeper which stress the door outwardly in the direction the door opens and also stresses the door compressively in the plane of'the door opening. i In testimony whereof I have affixed my signature.
